Terms of Service

1. Acceptance of Terms

The Service is provided by hrhelperg s.r.o. ("we," "our," or "us"), which owns and operates it under the name TwinPhone. References in these Terms to "TwinPhone" mean the TwinPhone service operated by hrhelperg s.r.o.

By accessing or using TwinPhone (twin-phone.com) and any related services (collectively, the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, you must not use the Service. We may update these Terms from time to time; material changes will be communicated via email or a prominent notice on the Service at least 30 days before taking effect. Continued use after the effective date constitutes acceptance.

2. Description of Service

TwinPhone provides browser-based voice calling to landlines and mobile phones worldwide. The Service may include outbound calling, virtual phone numbers, and team management features. Features may be added, modified, or removed at our discretion without liability.

3. Eligibility & Account Registration

You must be at least 18 years old (or the age of majority in your jurisdiction) to use the Service. By registering, you represent that all information you provide is accurate, current, and complete. You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You must notify us immediately of any unauthorized use. TwinPhone is not liable for any loss arising from unauthorized account access.

4. Billing & Credits

TwinPhone uses a pay-as-you-go credit system. Credits are purchased in advance and deducted per minute (rounded up) of call time at the rates published on twin-phone.com/en/rates at the time the call is placed. Credits do not expire. We reserve the right to change rates at any time; current rates are always displayed before you initiate a call. We will provide at least 7 days' notice of any rate increase via email to active users. Virtual numbers are billed monthly and may be cancelled at any time, with no further charges after cancellation.

All prices are in US Dollars (USD) unless stated otherwise. hrhelperg s.r.o. is currently not registered for VAT (neplátce DPH), so its prices do not include VAT. If hrhelperg s.r.o. becomes required to charge VAT or other applicable taxes based on your location (for example, EU VAT under the One-Stop Shop scheme once the applicable thresholds are met), the applicable tax will be calculated and shown before you confirm payment and itemized on your invoice. You remain responsible for any other taxes, levies, or duties imposed by your jurisdiction. Payments are processed by our third-party payment processor (Stripe, Inc.) and are subject to their terms of service. TwinPhone does not store credit card numbers or full payment credentials on its servers.

4.1 Promotional Top-Up Bonus

Eligible accounts may receive a one-time promotional bonus credit (the "Bonus Credit") added to their wallet on their first successful top-up, and we may offer additional tier bonuses on larger top-ups. Bonus Credit is promotional only: it has no cash value, is non-transferable, non-refundable, may expire, and may be revoked at our discretion in cases of abuse, including but not limited to creating multiple accounts from the same device, network, or payment method. Bonus Credit is not part of your refundable cash balance. The current bonus amounts and any eligibility conditions are displayed at the time of top-up; we may modify or discontinue the offer at any time without notice.

4.2 Auto-Refill (Optional)

Auto-refill is an opt-inservice. After a successful credit top-up, you may choose to enable auto-refill so that we automatically charge your saved payment method for a fixed amount (default $10.00) whenever your wallet balance falls below a threshold you select (default $2.00). By clicking "Enable auto-refill", you expressly authorize TwinPhone to charge the payment method on file for the configured amount, on a recurring basis, until you disable the feature.

You can change the amount, change the threshold, or turn auto-refill off at any time, from any device, in Account Settings → Billing. Cancellation takes effect immediately and prevents any further auto-refill charges. We will send an email receipt for every auto-refill charge. If three consecutive auto-refill attempts fail (e.g., expired card, insufficient funds), we will automatically disable the feature on your account and notify you by email.

Auto-refill purchases are subject to the same 14-day money-back guarantee as one-time top-ups (Section 5) and are governed by the FTC Restore Online Shoppers' Confidence Act (ROSCA) and Article 22 of the EU Consumer Rights Directive. You will not be charged for auto-refill until you actively opt in; this Section 4.2 by itself does not authorize any recurring charge.

5. Refunds & 14-Day Money-Back Guarantee

5.1 Guarantee Period

TwinPhone offers a 14-day money-back guarantee on all credit purchases. If you are unsatisfied with the Service for any reason, you may request a full refund of your most recent credit purchase within 14 calendar days of the transaction date, provided that no more than 30% of the purchased credits have been consumed at the time of the request.

5.2 How to Request a Refund

To request a refund, use the "Get Refund" feature in your Account Settings or email support@twin-phone.com with the subject line "[Refund Issue]". Include your account email and a brief description of the reason. Refunds are processed within 10 business days to the original payment method.

5.3 Refund Eligibility & Exclusions

We reserve the right to decline a refund request under any of the following circumstances:

• The request is made more than 14 calendar days after the purchase date.
• More than 30% of the purchased credits have already been used.
• The account has a pattern of repeated refund requests (more than two approved refunds within any 90-day period), which we consider indicative of abuse.
• The credits were obtained through a promotional offer or bonus that explicitly states non-refundability.
• The account has been suspended or terminated for violation of these Terms, including but not limited to breach of the Acceptable Use policy (Section 6).
• We have reasonable grounds to believe the request is fraudulent, made in bad faith, or is part of a chargeback or payment dispute scheme.

5.4 Virtual Numbers & Subscriptions

Virtual phone number monthly fees are non-refundable for the current billing period once the number has been provisioned. If a virtual number fails to function as described, you may request a credit or prorated refund by contacting support within 7 days of the billing date.

5.5 EU & UK Statutory Rights

If you are a consumer in the European Union, the United Kingdom, or any jurisdiction that provides a statutory right of withdrawal, this policy does not limit any mandatory refund or cancellation rights you may have under applicable consumer protection law. Under the EU Consumer Rights Directive (2011/83/EU) and equivalent UK rules, you have a 14-day right of withdrawal for digital services purchased online. Where you have expressly consented to the immediate provision of the Service and acknowledged the loss of your withdrawal right, the statutory right of withdrawal may not apply to credits already consumed. However, any unused credits remain eligible for refund in accordance with your statutory rights.

6. Acceptable Use

You may not use the Service for:

• Automated, auto-dialed, or robocalling
• Unsolicited bulk or commercial calls (spam)
• Fraudulent, deceptive, or misleading activity
• Harassing, threatening, or abusive communications
• Impersonating any person or entity
• Transmitting malware or interfering with the Service infrastructure
• Any activity that violates applicable local, state, national, or international laws
• Circumventing rate limits, security measures, or usage restrictions

You are solely responsible for the content of your communications and for your conduct on any call you place through the Service, including any information you provide, statements you make, or keypad (DTMF) selections you enter when interacting with a live agent, business, automated menu (IVR), bank, or government or visa service. You must not impersonate any person or entity, provide false, fraudulent, or misleading information to a called party, or use the Service to make any unlawful request or statement. TwinPhone transmits your call but does not monitor, script, or control what you say or send; responsibility for it rests with you.

We reserve the right to immediately suspend or terminate accounts that violate these terms, without prior notice and without refund, at our sole discretion. We may also report violations to law enforcement authorities where appropriate.

7. Intellectual Property

The Service, including its design, text, graphics, logos, software, and all underlying technology, is the property of TwinPhone or its licensors and is protected by intellectual property laws. You are granted a limited, non-exclusive, non-transferable, revocable license to use the Service for its intended purpose. You may not copy, modify, distribute, reverse-engineer, or create derivative works from any part of the Service without our prior written consent.

8. Service Availability & No Emergency Services

We strive for high availability but do not guarantee uninterrupted, timely, secure, or error-free service. Call quality depends on your internet connection, hardware, browser, and the destination telecom network — factors outside our control. We may perform scheduled or unscheduled maintenance at any time.

IMPORTANT: TwinPhone is NOT a replacement for traditional telephone service. TwinPhone does NOT support calls to emergency services (such as 911, 112, 999, or any local emergency numbers). You must maintain an alternative means of contacting emergency services at all times. TwinPhone shall have no liability for any inability to reach emergency services.

9. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND FREEDOM FROM COMPUTER VIRUSES OR OTHER HARMFUL CODE. TWINPHONE DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR THAT DEFECTS WILL BE CORRECTED. YOU USE THE SERVICE ENTIRELY AT YOUR OWN RISK.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL TWINPHONE, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AFFILIATES, SUPPLIERS, OR LICENSORS (COLLECTIVELY, "TWINPHONE PARTIES") BE LIABLE FOR ANY:

• INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES
• LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES
• COST OF PROCUREMENT OF SUBSTITUTE SERVICES
• DAMAGES ARISING FROM SERVICE INTERRUPTION, DATA LOSS, OR SECURITY BREACHES
• DAMAGES ARISING FROM THE CONDUCT OF ANY THIRD PARTY ON THE SERVICE

ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SERVICE, REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR OTHERWISE), EVEN IF ANY TWINPHONE PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

THE TOTAL AGGREGATE LIABILITY OF THE TWINPHONE PARTIES FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL AMOUNT YOU HAVE PAID TO TWINPHONE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) TEN US DOLLARS (USD $10.00).

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES OR WARRANTIES. IN SUCH JURISDICTIONS, OUR LIABILITY SHALL BE LIMITED TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW. NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, FRAUD, OR ANY LIABILITY THAT CANNOT BE EXCLUDED BY LAW.

11. Indemnification

You agree to indemnify, defend, and hold harmless the TwinPhone Parties from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees and court costs) arising from or related to: (a) your use or misuse of the Service, (b) your violation of these Terms or applicable law, (c) your violation of the rights of any third party, (d) any content or data you transmit through the Service, or (e) any fraudulent or illegal activity conducted through your account. This indemnification obligation survives termination of your account and these Terms.

12. Termination

You may close your account at any time through your account settings or by contacting us. We may suspend or terminate your account at any time for cause (including but not limited to breach of these Terms, fraudulent activity, or non-payment). Where permitted by law, we will provide reasonable notice before termination, except in cases requiring immediate action to protect the Service or other users.

Upon termination by you (voluntary closure), any remaining unused credits that were purchased within the preceding 14 days are refundable under our 14-Day Money-Back Guarantee (Section 5). Credits older than 14 days are non-refundable upon voluntary closure, except as required by applicable law or as set forth in Section 5.5.

Upon termination for cause by TwinPhone, remaining credits are forfeited, except where applicable law requires otherwise. Your right to use the Service ceases immediately, and we may delete your account data in accordance with our Privacy Policy after the retention period described therein. Sections 9 through 17 of these Terms survive termination.

13. Force Majeure

TwinPhone shall not be liable for any failure or delay in performance resulting from causes beyond our reasonable control, including but not limited to: natural disasters, acts of government, war, terrorism, pandemics, labor disputes, internet or telecom infrastructure failures, power outages, cyberattacks, or actions of third-party service providers.

14. Governing Law & Dispute Resolution

These Terms are governed by the laws of the Czech Republic, without regard to its conflict of laws principles. If you are a consumer, this choice of law does not deprive you of the protection afforded by the mandatory provisions of the law of your country of habitual residence (Article 6 of the Rome I Regulation and equivalent rules).

Consumers (EU, UK & elsewhere):You may bring proceedings in the courts of your country of habitual residence, and we will bring any proceedings against you only in those courts. Nothing in these Terms affects your statutory rights as a consumer that cannot be waived or limited by contract. You may also use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr.

Business (non-consumer) users: For users acting in the course of a business or profession, the courts of Prague, Czech Republic, have exclusive jurisdiction over any dispute arising out of or related to these Terms or the Service.

US users: If you are located in the United States, any dispute may, at your option or ours, be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) on an individual (non-class) basis, conducted in English. Nothing in this section limits your right to bring claims before your local consumer protection agency or small claims court where eligible. Class, consolidated, and representative proceedings are waived only to the extent permitted by applicable law.

15. Severability

If any provision of these Terms is found to be unenforceable or invalid by a court of competent jurisdiction, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.

16. Entire Agreement

These Terms, together with the Privacy Policy and Cookie Policy, constitute the entire agreement between you and TwinPhone regarding the Service and supersede all prior agreements, understandings, and representations. No waiver of any provision shall be deemed a continuing waiver or a waiver of any other provision.
